Question

True or False A computer will be more efficent if its processor has fewer cores

Answer 1

false.

Answer 2

It depends on how you mean by "efficient". In terms of power consumption…less cores is generally better to have fewer because you have in essence two or more CPUs running at the same time. However, great leaps have been made by Intel to make exceptionally efficient multi-core processors. In terms of processing, often more cores is much more efficient, provided the software used is capable of utilising multiple cores. This software is "multithreaded" meaning that it can accurately spread the processing across more than one core (or processor). Most more recent software makes full use of this.

Answer 3

More cores \(\leftrightarrow\) more efficient, in terms of performance
